Adelaide no match for Gamba's experience

Adelaide United coach Guillermo Amor says Gamba Osaka's Asian Champions League experience may have been too much for his side following its 3-0 loss at Coopers Stadium on Wednesday night.

The Japanese giants were too good for Adelaide in their opening Group H clash and Amor felt Gamba's big stage familiarity was the difference.

The J.League side has competed in eight Asian Champions League campaigns since their first appearance in 2006 and won the tournament in 2008 when they defeated Adelaide United 5-0 on aggregate in the final.

The gap in experience was also highlighted with Reds midfielders, 18 year-old Riley McGree and 19 year-old Jordan O'Doherty facing off against Japanese football icon, 37 year-old Yasuhito Endo who has racked up over 500 J.League appearances and 150 caps for Japan.
